# List of birds of Easter Island

This is a list of the bird species of Easter Island. The avifauna of Easter Island (Rapa Nui) include 51 species, of which 6 have been introduced by humans.

This list's taxonomic treatment (designation and sequence of orders, families and species) and nomenclature (common and scientific names) follow the conventions of The Clements Checklist of Birds of the World, 2022 edition. The family accounts at the beginning of each heading reflect this taxonomy, as do the species counts found in each family account. Introduced and accidental species are included in the total counts for Easter Island.

The following tags have been used to highlight several categories. Not all species fall into one of these categories. Those that do not are commonly occurring native species.

* (A) Accidental - a species that rarely or accidentally occurs on Easter Island
* Extinct - a species extinct to Easter Island
* (I) Introduced - a species introduced to Easter Island as a consequence, direct or indirect, of human actions
* (Ex) Extirpated - a species that no longer occurs in Easter Island although populations exist elsewhere

## Tinamous

Order: Tinamiformes Family: Tinamidae

The tinamous are one of the most ancient groups of bird. Although they look similar to other ground-dwelling birds like quail and grouse, they have no close relatives and are classified as a single family, Tinamidae, within their own order, the Tinamiformes. They are distantly related to the ratites (order Struthioniformes), that includes the rheas, emus and kiwis.
